Totally. Migrating anything is a PITA, even if it's simple. If it's complex and involves tons of code changes to eliminate "lock in", or more likely, move from one flavor of lock-in to another, you better think seriously whether it's even worth bothering.

Developer time is very, very expensive, and any time you spend "migrating" is time not spent building features that add value. Except in rare cases, the end customer probably doesn't care if your stuff runs on AWS, GCP, or Azure.
